Semantic analysis (compilers)

Semantic analysis, also context sensitive analysis, is a process in compiler construction, usually after parsing, to gather necessary semantic information from the source code. It usually includes type checking, or makes sure a variable is declared before use which is impossible to describe in Extended Backus–Naur Form and thus not easily detected during parsing.

Implementation

• Haskell: usually with the help of Monad (functional programming) and applicative functor
